Transparent metamaterial for energy-efficient regulation in building can clean itself like a lotus leaf
2024-07-11 05:10:41
Researchers at the Karlsruhe Institute of Technology (KIT) introduce a polymer-based material with unique properties in the journal Nature Communications. This material allows sunlight to enter, maintains a more comfortable indoor climate without additional energy, and cleans itself like a lotus leaf. The new development could replace glass components in walls and roofs in the future. The research team has successfully tested the material in outdoor tests on the KIT campus.
Extending the lifespan of lithium-metal batteries using a fluorinated ether diluent
2024-07-11 05:10:41
The design of battery technologies with increasingly longer lifespans could help to meet the growing needs of the electronics and automotive industry. Lithium (Li) batteries are the most widely used rechargeable batteries worldwide. Thus, devising strategies that can increase their longevity could be far easier than designing entirely new batteries.
To 6G and beyond: Engineers unlock the next generation of wireless communications
2024-07-11 05:10:40
In the early 2010s, LightSquared, a multibillion-dollar startup promising to revolutionize cellular communications, declared bankruptcy. The company couldn't figure out how to prevent its signals from interfering with those of GPS systems.
Research reveals scale of the EU's dependency on imports for critical minerals needed for green transition
2024-07-11 05:10:39
The climate transition is a materials transition. Decades of international diplomacy around oil, gas and pipelines are now giving way to conversations around the supply of critical raw materials. And not before time: to meet the EU's energy and climate targets, we need to build the right technologies, in the right quantities, at the right speed. The problem is that many of these technologies are built with materials imported from just a handful of countries.
Battery storage is key to scaling up solar and wind power. Here's why.
2024-07-11 01:09:15
As the U.S. transitions away from coal and gas, battery storage is crucial for making the power grid reliable.

Promising material for solar energy gets its curious boost from entropy, researchers show
2024-07-10 16:44:54
Solar energy is critical for a clean-energy future. Traditionally, solar energy is harvested using silicon—the same semiconductor material used in everyday electronic devices. But silicon solar panels have drawbacks: for instance, they're expensive and hard to mount on curved surfaces.
New model predicts impact of reconfigurable intelligent surfaces on radio wave propagation
2024-07-10 16:44:54
A method to analytically express the performance of wireless communication systems when using reconfigurable intelligent surfaces (RIS) has been successfully developed by researchers at Tohoku University, the University of Surrey, and the University of Nottingham.
Q&A: Ghana is planning its first nuclear energy plant—what's behind the decision?
2024-07-10 15:57:30
Ghana is considering bids from five companies for the construction of what would be its first nuclear power plant. The companies are: France's EDF, US-based NuScale Power and Regnum Technology Group; China National Nuclear Corporation; South Korea's Kepco and its subsidiary Korea Hydro Nuclear Power Corporation; and Russia's Rosatom. The Conversation Africa's Godfred Akoto Boafo interviewed Seth Kofi Debrah, director, Nuclear Power Institute, Ghana Atomic Energy Commission, on the pros and cons of adding nuclear power to the country's power mix, and why Ghana needs to diversify and identify new energy sources.
